LOS ANGELES—The former owner of a notorious “revenge porn” website and another California man have been charged with stealing nude photos from hundreds of hacked email accounts and posting the images online.

The FBI arrested 27-year-old Hunter Moore of Woodland and 25-year-old Charles Evens of Studio City on Thursday.

Evens pleaded not guilty in Los Angeles. Moore appeared in court in Sacramento but didn’t enter a plea.

Moore ran a now-defunct website called isanyoneup.com that posted explicit photos, including some submitted by revenge-minded ex-spouses and lovers without permission of the people depicted.
